Corporate Treasury Statement Reconciliation

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Reading mode (RUNBOOK): Run these steps in order. The forecast-accuracy step scores forecasts against the actual amounts the reconciliation step just produced, so reconciliation has to run first.

Linear two-step chain for TMS straight-through reconciliation. Step 1 classifies ISO 20022 camt.053 BkTxCd entries (Domain/Family/SubFamily), validates the OPBD+Σ=CLBD balance equation, and scores structured-remittance match rate against the CGI-MP camt.053 Usage Guide v5.0. Step 2 scores AFP Cash Forecasting Survey 2024 MAPE and directional bias of the treasury cash forecasts against the reconciled actual transaction amounts, closing the TMS forecast-vs-actual cycle. No personal data is processed.

camt.053 Statement Reconciliation art-258-parse-camt053-reconciliation

Classifies BkTxCd Domain/Family/SubFamily per ISO 20022 ExternalBankTransactionCode1Code registry 2023-03. Validates balance equation OPBD + Σ movements = CLBD. Scores structured-remittance match rate. Emits reconciliation_status (CLEAN/PARTIAL_MATCH/LOW_MATCH_RATE/FAILED_BALANCE), match_rate_pct, and per-bucket transaction counts. Output passed as actuals context to Step 2.

Cash Forecast Accuracy Scoring art-263-score-cash-forecast-accuracy

Scores treasury cash forecast accuracy by MAPE and directional bias across T+1/T+7/T+30/T+90+ horizon buckets. Forecasts are built from Step 1's reconciled actual transaction amounts. Detects persistent timing bias (>75% same-sign errors). Returns overall_accuracy_tier (EXCELLENT/GOOD/ACCEPTABLE/POOR per AFP 2024), by_horizon breakdown, timing_bias_detected. Final stage.

Question: The bank statement closed at 10500 against a 10000 opening balance. Does the closing balance tie to opening plus booked activity? Run the AINumbers MCP tool `run_chain` with {"chain":"corporate-treasury-statement-reconciliation"} and read `art-258-parse-camt053-reconciliation.reconciliation_status`. Re-run with `inputs` for `art-258-parse-camt053-reconciliation`, reusing the values that result echoed, with `transactions` changed so it carries no transactions, so the closing balance cannot tie. Compare the same field. Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`. Ledger, for a human re-check: https://ledger.ainumbers.co/ PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
